Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491002, here are decompositions:

11 + 490991 = 491002
53 + 490949 = 491002
89 + 490913 = 491002
173 + 490829 = 491002
233 + 490769 = 491002
269 + 490733 = 491002
359 + 490643 = 491002
383 + 490619 = 491002

Showing the first eight; more decompositions exist.
